ldapadd is slow, or what?

Hi
How long does it take to add one entry with the command
ldapadd -w secret -v -D "cn=Manager,o=aalug,c=dk" -f /test.ldif
where test.ldif contains
dn: ou=imap,ou=intranet,o=aalug,c=dk
ou: imap
objectclass: organizationalUnit
it took about 2 minuts and 30 secs at my i686 (pentium 2 350mhz 64 mb ram)
I'm going to use ldap on a system where online modifications and additions
are essentiel, I know the speed of slapadd :-)
